[Diy_efi] Interceptor/ECU progress

Mon Mar 12 07:25:35 UTC 2007

2 engine boat - sounds like a real 'fun' (read that as spooky fast)
ride :-)

I am indeed playing in new areas/designing my own ECU - your needs may
be met by something already off the shelf today - megasquirt comes
immediately to mind. That may be the ticket for you. At least today so
to speak - my stuff is not ready for prime time in any way - serious
assembly required :-) A few more months and that will change - today
it's still rocket surgery :-)
